To 11.7] 1071/01 2'25 'nmq con/(707w..-

Be it known that I, Josnrii H. Corn, a eiti zen of the United States of America, residing at New 'indsor, in the county of \Veld and State of Colorado, have invented certain new and useful Improvements in Hay-Stackers; and i do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer- 1 vantageously applied to the pivoted frame carrying the stacker-head during the act of raising the said head and its load. 1 accomplish this result by the employment of a revolving frame over which the lifting-cable passes, this frame being connected with the pivoted frame. As the stacker-head is lifted the pivoted frame revolves on an axis which at the beginning of the operation passes through the lower part of the frame, while at the end of the operation the axis is above the body i of the revolving frame, the upper extremity of the latter having turned downwardly underneath the pivotal center during the lifting operation. The revolving frame is weighted at one extremity to facilitate the initial return movement of the parts at the end of each lifting operation.

In the construction shown in the drawings a stacker-head is attached to bars slidably coiinected with bars of the pivoted frame. The

sliding bars are connected with arms pivoted 3 on the framework and arranged to extend the stacker-head or give it an outward or upward movement simultaneously with the lifting operation. This extensible feature of the stacker is, however, protected by Letters Patent No. 701,257, issued to me May 27, 1902, and therefore nothing is claimed, broadly, thereon in this specification.

l-laving briefly outlined my improved construction, together with its operation and function, 1 will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation showing my improved stacker in the normal position or when the stacker head is down ready to receive its load of hay. Fig. 2 is a top or plan view of the same and in the same position. Fig. 3 shows the stacker-head in the lifted position and the other parts in the corresponding position. In this view the stacker-head is broken away. i F ig. A shows the part broken from Fig. 3. Figs. 5 and 6 are top and side views, respectively, of the revolving frame shown in detail. Fig. 6 is a side elevation. of the machine, partly broken away, illustrating a yielding device engaged by the pivoted frame as it approaches its upward limit of movement. Fig. 7 is a fragmentary view, slightly enlarged, looking in the direction of the arrow 7 in Fig. 6. Fig. 8 is a view looking in the direction of the arrow 8 in Fig. 7.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the framework, which may be of any suitable construction.

i This framework is stationary during the operation of the machine, but is mounted on runners (i to facilitate moving it about from place to place, the frame 5 being provided with front and rear upright bars 5 and horizontal bars 5". connecting the upright bars 5.

The part of the structure heretofore referred to as the pivoted frame is provided with side bars 7, pivoted at their rear extremities on the stationary frame, as shown at 8. As shown in the drawings, these bars 7 are pivoted on the extremities of a rod or bar 8, extending transversely of and mounted in the stationary frame. The lifting-frame is reinforced or strengthened by two horizontallyinclined side bars 7 forming braces, the said side bars being connected by a cross-bar 7 the latter being mortised into the bars 7 of the pivoted frame. Upon the bars 7 are slidably mounted bars 9, which are connected with the bars 7 by metal straps 10, which are secured to the bars 9, but passed around and slide freely on the bars 7. Pivotally connected with the bars 9, as shown at 12, are arms 13, whose rear extremities are pivotally connected with the rear or upright part of the frame at a suitably-elevated point, as shown at 14:. The bar 13 is provided with openings 13* for purposes of adjustment.

In the upper part of the stationary frame 5 is mounted a shaft 15, which extends transversely of the frame. On this shaft is revolubly mounted the frame 16, heretofore referred to as the revolving frame. This frame may be of any suitable construction adapted to perform the function heretofore outlined. As shown in the drawings, the frame 16 has the general shape of a triangle in side View, the apex of the triangle being uppermost when the stacker-head 27 is 'down (see Fig. 1) and lowest when the stacker-head is raised. (See Fig. 3.) The construction of this revolving frame will be described in detail, though it must be understood that the invention is in no way limited to these details. The base of this frame (referring to the lower 1 part when the stacker-head is down) is provided with two separated bars 16, Whose forward extremitiesfsee Figs. 1, 2, 5, and 6) are connected by a rod or shaft 16. The bars 16 approach each other as they extend rear- 7 wardly, their rear extremities being connected by a weight 17, preferably composed of metal and forming a counterbalance. Occupying the same plane as the bars 16* are two separated parallel bars 16, whose forward extremities are also connected by the rod 16", while their rear extremities are connected by a transverse bar 16. Projecting upwardly from the base and forming the apex of a triangle on each side are two inclined bars 16 and 16, which are connected at the top by a cross-bar 16 The two inclined bars just named on one side of the frame are connected with the same bars on the opposite side of the frame by a rod 16. The lower extremities of the bars l6 and 16 are suitably secured to the base of the frame. The base and upper part of the frame are further connected and braced by cross-bars 16", which are connected at their intersection by bolts 16. The rod or shaft 15, forming the axis of the frame, passes through the two base-bars 16 and the two base-bars 16, all of which bars occupy the same plane, as heretofore explained. The rod or shaft 16 of the revolving frame is connected with a cross-bar 18 of the pivoted frame by a centrally-located rod 19 and a link 19*.

As shown in the drawings, a double cable composed of two members 20 is employed in lifting the stacker-head. These cable members are connected with the forward extremity of the pivoted frame, as shown at 21, with the shaft 16 as shown at 22, and passed thence over the top of the frame 16, engaging the cross bar 16 thence rearwardly and downwardly engaging the rear or weighted end of the revolving frame, and thence downwardly around a guide-pulley 23, mounted on the stationary frame, and thence outwardly. In practice a horse is hitched to this cable, whereby the necessary lifting power is obtained. The description of the arrangement of the cable with reference to the revolving frame must be understood as referring to the position of the parts when the stacker-head is down. When the stacker-head is raised, the revolving frame is in the position shown in Fig. 3, the cable having left the cross-bar 16 of the revolving frame.

It will be understood that the pulley 23 is placed conveniently low on the stationary frame for applying the power, as heretofore stated. The function of the revolving frame 16 is to form a structure which supports the cable in an advantageous position until the stacker-head is sufficiently raised to no longer need the revolving frame in applying the power, in which event the revolving frame moves downwardly and takes the position shown in Fig. 3. Its weighted end then occupies a forward position, and as soon as the pull of the cable on the stacker-head ceases to act after the stacker-head is raised the weight will start the stacker-head downwardly, thus making the reverse or downward movement automatic.

Each of the side bars 7 of the pivoted frame is provided with a stop 28, adapted to engage the rear part of the stationary frame when the stacker-head is raised to the position shown in Fig. 3 of the drawings. The object of this stop is to prevent the stacker-head from moving too far rearwardly. The stop is adjustable by means of a set screw 29, passed through a slot 30, formed in the stop.

In Figs. 6, 7, and 8 a yielding means is connected with the revolving frame or device for the purpose of cushioning the pivoted frame and the stacker-head as the said frame and head approach their upward limit of movement, thus relieving the mechanism from shock or jar incident to sudden stoppage. Where this construction is employed, I connect the sides of the revolving frame at its forward extremity (referring to its uppermost position) by a bar 31. In the forward extremity of each bar 16 is journaled a crank 32, with which a rod 33 is connected at its upper extremity, the lower extremity of each rod being connected with the forward end of the pivoted frame by a link 34. The outer extremity 32 of each crank 32 is connected,

movement the cranks justdescribed have assumed the position shown in Figs. 6. 7, and 8 of the drawings, and as. the pivoted frame approaches the arms or bars 13 engage the extremities 32 of the cranks 32 and the springs 34 yield, relieving the mechanism from any injurious jar which otherwise might be incident to the sudden stopping of the frame upon reaching its upward limit of movement, as in ordinary constructions of this class.

I claim is- 1. In a stacker, the combination with a rela tively stationary framework, of a pivoted frame for raising the stacker-head, a cable connected with the latter, and a revolving frame mounted to turn on the stationary frame during the movement of the stacker-head, the said revolving frame being engaged by the cable to support and guide the same during the operation of lifting the stacker-head, whereby the power is advantageously applied, and a rod connecting the stacker-head and the revolving frame, the extremities of the rod bej ing movably connected with the respective 1 parts.

2. In a stacker, the combmation with a relatively stationary framework, a pivoted frame l l l connected with the stacker-head, and a cable connected with the latter, of a revolving frame mounted on the stationary frame and extending above the same when the stacker-head is down, a rod connecting the revolving frame with the stacker-head, the lifting-cable passing over and engaging the revolving frame during the lifting operation for the purpose of supporting the cable to advantageouly apply the power, the stationary frame being open below the axis of the revolving frame to allow the latter to move downwardl as the stackerhead approaches its upward limit of movement.

3. In a stacker, the combination with a framework, a pivoted frame, a stacker-head connected therewith, and a cable also connected with the stacker-head, of a revolving frame mounted on the stationary frame and having its axis of rotation located forward of and above the pivot of the pivoted frame, the said revolving frame extending above its axis when the stacker-head is down and forming a support and guide for the lifting-cable, and a rod connecting the stacker-head with the revolving frame.
